Flow Measurement In Pipes Using Pressure Reducing Parts Manufacturer

Teaching objectives

Pressure losses generated when the water passes through three standardised pressure parts (venturi meter, diaphragm, rotameter) are measured, which allows the fluid flow rate to be calculated and compared with a volumetric measure. Comparison of the pressure drop from each measuring device. Comparison of the pressure drop produced by a sudden contraction and a 90° angled pipe.
